ELECTRICAL-WIRE STATION.

SPECIFICATION forming part of Letters Patent No. 756,850, dated April 12, 1904.

Appiicaion filed rune is, 1903.

To all whom t may concern:

Be it known that I, WILLIAM E. HAMILTON,

a citizen of the United States, and a resident of Columbus, in the county of Franklin, in the State of Ohio, have invented certain new and useful Improvements in Electrical-Wire Stations, Of which the following isaspecilication.

This invention relates more particularly to means for furnishing a convenient connection between electrical conductors and machines that are adapted to .be run by electricity and located at a distance from the mainv wires or conductors. Its objects are to provide an apparatus of the character indicated which will be simple and durable in construction and convenient to set up to form the desired electrical connections. It is also intended to take the place of expensive and cumbersome apparatus which employs insulated cable and is usually attached to the machines employing' electricity, such as are now commonly used. An example are those vused in mining which are located in chambers and receive their electrical-energy from ,wires in the main entry.

In the drawings accompanying this applica-l tion, Figure l is a front view of an apparatus embodying this invention shown in connection with a mine-post and illustrating the method of carrying the wire to the main entry. Fig. 2 is a side elevation of the s'arne shown with parts broken away and others in cross-section. Figs. 3 and 4 show front and sectional views, respectively, of amore elaborate form of construction adapted for use in factories or the like and is provided with a switchboard. Figs. 5 and 6 show further modified forms, and Fig. 7 is a sectional detail of a binding-post adapted to be used with this device.

As shown in Fig. 1, a post 8, such as commonly used in mines, is securely wedged by wedges 9 between the floor and roof of the mine in a position convenient to the machine to be operated, Rigidly secured to the post 8 are brackets 10, having spindles 11, formed either integrally therewith or secured thereto.

On the spindles 11 are'spools or reels 12, which are held in position by washers 13 and cotterpins 14. The reels 12 are preferably made of Serial No. 162,102. (No model.)

wood or other non-conductive material or may be insulated in any well-known manner from the brackets. On the reels 12 is wound a suficient amount of copper wire or other conductor 15 to reach from the cross-entry to the faceof the room or as far in as necessary to connect with the short insulated cable 16, leading to the machine to be operated. The wire 15 passes through the binding-post 17, by,

means of which it may be clamped at any desired point. p The binding-post 17 is formed in any suitable manner, so that the wire will be insulated from the iron bracket and make an electrical connection with the short cable 18, which connects from the binding-post 17 to a terminal post 19, as shown in Fig. 1. This terminal post is similar to the post 17 and provides means for connecting the cable 18 to the insulated cable 16, which connects directly with the machine to be operated. A dog or pawl 2O is pivoted at 21 to the bracket 10 and is adapted to engage the lower surface of the reel 12 to prevent the same from unwinding when not desired.k

, In the device shown in Figs. 3 and 4 the bracket 22 is adapted to carry two reels 23, and for this purpose is prov-ided with lugs or arms 24, which areprovided with holes for a pipe or other spindle 25, which is held by means of pins 26 to carry the reels 23. The reels are provided with retaining-pawls as above described. At the base of the bracket is a switchboard 27, which is provided with binding-posts 28, with which the various cables connect, as above described.

In the modifications shown in Figs. 5 and 6 the general arrangement is substantially the same. In Fig. 5 the double bracket 29 is provided with vertical reel-spindles 30, as shown in Fig. 2, and with binding-posts 31 for the cable connections, as above described. In Fig. 6 the arrangement is substantially as heretofore. described, but the reels 32 are mounted on horizontal spindles 33 on the brackets 34.

Any convenient form of binding-post may be used with this apparatus, but I have shown in Fig. 7 a preferred form of binding-post, in which a bolt 36, having its head countersunk in the bracket, carries an insulated sleeve 37,

around which the wires are bent. A clip or washer 38 around this sleeve is pressed against the wires to make a suitable contact by means of a recessed insulator 39, which engages the sleeve 37 and the bolt 36, and is clamped in position by means of a wing-nut 40.

Ihe method of installing and operating` this apparatus is as follows: The post 8 is rigidly secured in position, as shown in Figui. rlhe brackets carrying' the spindles are next fastened to the post at a suitable distance apart, and the reels, one of which contains the wire for the positive and the other the wire ior the negative connections, are placed in position. A sutiicient amount of the wire is then unwound to reach to the main conductors and is con-` nected therewith. The pawl having been depressed to allow the unwinding is released to prevent further unwinding and the post 17 securely clamped on the wire. It will be noted that it' the distance from the post to the main' conductor is too great for the strength of the wire, insulating-supports 35 may be provided at convenient distances. It is also obvious that the reel may be unwound to make connection with the main line and afterward placed in position on the spindle. W' hen the face of the room in which a machine-for instance, a coalcutting machine-has advanced so far that the short cable 16, which accompanies cach machine, dees not reach from the binding-post to the machine, the wedges are knocked out and the post carrying the reels is set nearer to the face. To do this, it is only necessary to loosen the binding-posts and disengage the pawls to allow the reels to unwind as they are moved forward. Then they are again set in position, the wire is clamped and the pawl engages the reel, as previously described.

Having thus described this invention, which I do not wish to limit to the exact forms or details of construction herein shown, what I claim, and desire to secure by Letters Patent, 1s
